If your job history has been unstable due to multiple temp jobs, some companies may be reluctant to hire you for fear you'll quickly move on. According to CareeRealism, you can avoid this by bunching your temporary jobs together on your resume

By listing these jobs as one work experience, you show that you've been consistently working and developing skills rather than just hopping from job to job. They advise:

"Rather than listing out every period of work for the 5 or 10 jobs you had, group it all together as one period of work. For instance, if you were doing contract work with five different clients, include the date you began contract work and the date you ended contract work, regardless of whether you were still working with same client"

The link has additional suggestions if your work history hasn't been consistent through no fault of your own.
